Employee Management System This exercise assumes you have created the Employee class for Programming Exercise 4. Create a program that stores Employee objects in a dictionary. Use the employee ID number as the key. The program should present a menu that lets the user perform the following actions: Look up an employee in the dictionary Add a new employee to the dictionary Change an existing employee’s name, department, and job title in the dictionary Delete an employee from the dictionary Quit the program When the program ends, it should pickle the dictionary and save it to a file. Each time the program starts, it should try to load the pickled dictionary from the file. If the file does not exist, the program should start with an empty dictionary.
- Problem 2: Route Planning You are on the development team for a Route Planning application. The team has already developed a class named NavigatorApp for storing and displaying the graph representing the road network. This class has a void displayShortestPath() function which takes the source and destination vertices of the trip and displays the shortest route between them. Using the strategy pattern, draw a class diagram of the system which will allow for the NavigatorApp to display the shortest driving, walking, or cycling route when the displayShortestPath() function is called. You can assume that another developer is in charge of making sure the appropriate strategy is correctly set and for calling the displayShortestPath() function Starter code /* Modify NavigatorApp (if necessary) */ class NavigatorApp { private: Graph map; public: void displayMap(Window * window); void displayShortestPath(Vertex source, Vertex destination, Window * window); /* write pseudo code for this function…True/ False 1- Class objects can be defined prior to the class declaration. 2- You must use the private access specification for all data members of a class. 3- If an array is partially initialized, the uninitialized elements will be set to zero. 4- A vector object automatically expands in size to accommodate the items stored in it. 5- With pointer variables, you can access but not modify data in other variables. 6- Assuming myValues is an array of int values and index is an int variable, both of the following statements do the same thing. 1. cout header file. 15- To solve a problem recursively, you must identify at least one case in which the problem can be solved without recursion.Pointer variable stores the address where another object resides and system will automatically do garbage collection.

Create a class FruitBasket 2. Create a stack object named basket 3. Ask the user to input the number of fruits he/she would like to catch 4. Ask the user to choose a fruit to catch by pressing 'A' for apple, 'o' for orange, 'M' for mango, and 'G' for guava 5. Display all the fruits that the basket has 6. Ask the user to Enter 'E' to start eating a fruit 7. Display the fruits remaining each time 'E' is entered and "No More Fruits" when the basket becomes emptyComputer Science using java The program has to evaluate arithmetic expressions using a BST for thatpurpose. The rules are the following:The program asks the user to enter an arithmetic expression in the infixformat. Then the program builds a BST for that expression. After buildingthe BST, a menu will be present to the user allowing him to: traverse the BST in inorder, traverse the BST in postorder, traverse the BST in preorder.Users will choose among the options present. The result will be thedisplay of the original arithmetic expression and the new one thatdepends on the option chosen. The program should repeat as long as theuser wants.
- DiceSet Class in Python Write a class named DiceSet that contains a list of Die objects. Fields dice a list of Die objects Methods __init__(self, dice_faces) The constructor should instantiate the dice list to an empty list if no parameters are set. The constructor should take a list of integers. Add one die to the dice set for each integer with the number of faces equal to the integer. pop_die(self, value) Remove and return the first die with the given value from the list. add_die(self, die) Adds the given die (of class Die) to the dice list. roll(self) Roll all the die objects in the list of dice and return their sum. die_values(self) Return a list of the int values (last rolls) of the dice in the list. __str__(self) returns a string version of a dice set. Example: "{[d3] 1, [d6] 4, [d12] 5, [d4] 3}"Library class: Fields: books as arraylist to store all the books available in the library B3 B1 B2 В4 B5 Constructor: Library() } : No parameterized constructor to create the books object Methods: 1. addBook(Book bookobj): to add a new book to the arraylist; send the book object as a parameter to this method. 2. searchBook(String name): search a book by a given name in the arraylist. if exits print bookX found; otherwise print not found!!! 3. RemoveBook(String name): to delete a book object from arraylist by a given name: Hint: you need to use iterator class and remove method. Book class: Fileds: bookld, bookname. Constructor: two parameterized constructor that accepts name a parameter Book(int ID, String name) ..... Methods: 1. Accessor method to return the name of the book 2. Mutator method to change the id of the book. Use this Main method: in your program: public static void main(String args[]) { Library lib=new Library(); lib.addBook(new Book("b1")); lib.addBook(new Book("b2"));…When a Course object is created, what is the value of the students pointer?
